Payment providers have test gateways and cards for you to test your code against. While it might be a minor convenience for you to have 'fake' cards in their production system, the only thing they have to gain is a potentially serious fraud loophole (at best), or an expensive footgun for you.
Don't "test" checkout flows in production unless you're using real credit cards :D
That's good advice.
